DETAILED DESCRIPTION

Disclosed is a bonding system for dispensing and curing an adhesiveagent and associated methods, systems, devices, and various apparatus.The bonding system includes a housing, a dispenser, and a curing device.It would be understood by one of skill in the art that the disclosedsystem is described in but a few exemplary embodiments among many. Noparticular terminology or description should be considered limiting onthe disclosure or the scope of any claims issuing therefrom. Directionalreferences such as “up,” “down,” “top,” “left,” “right,” “front,”“back,” and “corners,” among others are intended to refer to theorientation as illustrated and described in the figure (or figures) towhich the components and directions are referencing.

Adhesive bonding is a process of joining materials in which an adhesiveagent, which may be a liquid or semi-solid state material, is placedbetween the facing surfaces of the components to be joined to form anassembled product. The two components to be joined may be constructedfrom various materials such as various rubbers, metals, plastics,ceramics, glass, or various other materials. After the adhesive agent isapplied, the adhesive agent is cured such that the adhesive agentbecomes a solid. The adhesive agent is cured through application of acuring catalyst such as pressure, heat, ultraviolet (UV) light, water,or various other suitable curing catalysts depending on the type ofadhesive agent utilized. For example, radiation-cured adhesive agentsare a class of adhesives that become activated and curing is initiatedwhen exposed to radiation, usually in the form of UV light.

As part of their composition, adhesive agents commonly include variousvolatile organic compounds (VOCs). VOCs present a dangerous explosionhazard during the adhesive bonding process. To reduce the potential foran explosion, typical adhesive bonding processes separate an adhesiveagent dispensing step from a curing step such that the dispensing stepis typically performed at a location distinct from a location where thecuring step is performed. Separating the dispensing step from the curingstep and performing each step in separate and distinct locations reducesthe number of possible ignition sources that the VOCs of the adhesiveagent may react with and thereby reduces the potential for an explosion.However, by separating the application step from the curing step,significant time and resources are spent during the adhesive bondingprocess to move the items between the stations performing each step, toset up each station, to monitor each station, etc. Therefore, althoughseparating the dispensing step location from the curing step locationreduces the explosion potential, the efficiency of the overall processcan be greatly reduced.

The door 192 defines the door open position when the door 192 is spacedapart from the housing 102 and does not fully cover the profile of thechamber 104. FIG. 1 illustrates the door 192 in the door open position.The door 192 in the door open position defines a clearance between thedoor 192 and the front chamber opening 130. The clearance between thedoor 192 and the front chamber opening 130 includes embodiments wherethe door 192 is angled open with an edge of the door 192 contacting aportion of the housing 102 and an opposite edge of the door 192 isspaced apart from the housing 102. When the door 192 is in the door openposition, the clearance between the door 192 and the front chamberopening 130 allows the operator to gain access to the chamber 104. Asillustrated in FIG. 1, in the door open position, the back side 198 ofthe door 192 is spaced apart from the front side 118 of the housing 102in various embodiments.

The door 192 defines the door closed position when the door 192 ispositioned adjacent to the housing 102 and fully covers the profile ofthe chamber 104. FIG. 2 illustrates the door 192 in the door closedposition. In various embodiments, in the door closed position, the door192 covers the profile of the chamber 104 at the front side 118 of thehousing 102. As illustrated in FIG. 2, in various embodiments, in thedoor closed position, the back side 198 of the door 192 is positionedadjacent to the front side 118 of the housing 102.

In various embodiments, in addition to being pivotable relative to thehousing 102 through the rotating rod 109, the door 192 is also axiallypositionable along the venting bolts 202 a,b. In various embodiments, adistance along the venting bolts 202 a,b between the bolt heads 204 a,band the securing rods 107 a,b, respectively, is greater than a width ofthe door 192. Accordingly, the door 192 may be positionable along theventing bolts 202 a,b between the securing rods 107 a,b and bolt heads204 a,b, respectively. In various embodiments, because the door 192 isaxially positionable along the venting bolts 202, while in the doorclosed position, the door 192 is movable between a sealed position and avented position.

In the sealed position, the door 192 covers the profile of the chamber104 and contacts the front side 118 of the housing 102 surrounding thefront chamber opening 130. The sealed position is illustrated in FIG.19. In the sealed position, the gasket 138 positioned at the front side118 of the housing 102 forms a seal between the door 192 and the housing102 such that the chamber 104 is sealed. In various embodiments, theback side 198 of the door 192 contacts the front side 118 of the housing102 in the sealed position. In the sealed position, as described belowwith reference to FIG. 5, gaps 506 a,b (illustrated in FIG. 5), aredefined between the spacers 206 a,b and the bolt heads 204 a,b,respectively.

In the vented position, the door 192 covers the profile of the chamber104 and defines a venting gap (not illustrated) around a periphery 302(illustrated in FIG. 3) of the door 192. The venting gap extends fromthe periphery 302 of the door 192 to the chamber 104 between the door192 and the front side 118 of the housing 102 surrounding the frontchamber opening 130. In various embodiments, the venting gap is definedbetween the back side 198 of the door 192 and the front side 118 of thehousing 102 around the periphery 302 of the door 192. In variousembodiments, the venting gap is defined between the gasket 138 and theback side 198 of the door 192. In various embodiments, the venting gaphas a gap width which may be approximately the same as the gap width ofthe gaps 506,508. Because the back side 198 of the door 192 is spacedapart from the front side 118 of the housing 102 to form the ventinggap, the gasket 138 does not create a seal between the door 192 and thehousing 102. Accordingly, airflow through the front chamber opening 130via the venting gap is permitted. In the vented position, the bolt heads204 a,b of the venting bolts 202 a,b may contact the spacers 206 a,b,respectively.

In various embodiments, the door 192 is movable from the sealed positionto the vented position when an explosion occurs within the chamber 104.Accordingly, the vented position of the door 192 enables the bondingsystem 100 to reduce the impact of a potential explosion within thechamber 104. The vented position also provides an explosion resistantventing system that is reliable and repeatable because the ventingsystem may be examined in real time after each dispensing and curingoperation.

Chambers designed to control explosion hazards typically includesufficient natural or mechanical air ventilation to limit theconcentration of flammable gases or vapors to some percentage of theirless than explosive limit (LEL), which is the high or low concentration(or percentage) of gas or vapor in the air capable of producing anexplosion in the presence of an ignition source, which may typically beless than 5% concentration or greater than 95% concentration. However,in the present embodiment, because a vacuum is created within thechamber 104 during the adhesive bonding process, reduced levels ofambient air are within the chamber to limit the LEL within the chamber.Accordingly, the vacuum within the chamber 104 may actually increase thepotential for the explosion hazard during the adhesive bonding process.

The potential for an explosion within the chamber 104 may be reduced bylimiting the possible ignition sources within the chamber 104. Forexample, the potential for an explosion may be reduced by throughvarious steps including, but not limited to: utilizing a rotator 152with a brushless rotation drive motor 129; positioning the adhesivesupplier 140 external to the chamber 104 while the dispenser 106 is atleast partially positioned within the chamber 104; and positioning thecuring catalyst activation source of the curing devices 108 external tothe chamber 104 while the emitting ends 806 of the curing devices 108are positioned within the chamber 104. However, because the dispensingand curing of the adhesive agent occur in the same environment, thepotential for an explosion still remains.

In the event that the VOCs of the adhesive agent react with an ignitionsource causing an explosion, the door assembly 190 may reduce the impactof the explosion. The force of the explosion within the chamber 104moves the door 192 from the sealed position to the vented position andbreaks the seal between the door 192 and the housing 102. In variousembodiments, moving the door 192 to the vented position permits ventingof the chamber 104.

The locking arm 194 defines the arm open position when the locking arm194 is positioned away from the housing 102. The arm open position isillustrated in FIG. 1.

In various embodiments, moving the locking plunger502 into the extended position moves the door 192 in the closed positionfrom the vented position to the sealed position. In various embodiments,the locking plunger 502 remains in the extended position while the door192 is in the sealed position and acts as a biasing element to keep thedoor 192 in the sealed position; however, in various other embodiments,the locking plunger 502 may return to the retracted position afterpositioning the door 192 in the sealed position.

In the retracted position, as illustrated in FIG. 19, the base 1906 isat least partially retracted within the locking head 121. In variousembodiments, the door 192 may be in the sealed position or the ventedposition when the locking arm 194 is in the retracted position. When thedoor 192 is in the sealed position and the locking arm 194 is in theretracted position, as illustrated in FIG. 19, the plunger surface 504is spaced apart from the front side 196 of the door 192 such that thelocking plunger 502 is not engaged with the door 192. When the door 192is in the vented position and the locking arm 194 is in the retractedposition, the plunger surface 504 is engaged with the front side 196 ofthe door 192.

The locking arm 194 may be utilized to retain the door 192 in the closedposition, whether in the sealed position or the vented position. Invarious embodiments, the locking plunger 502 may act as a dampener forthe door 192 by engaging the front side 196 of the door 192.Accordingly, the locking plunger 502 may help retain the door 192 on theventing bolts 202 and dampen the impact of the door 192 contacting thebolt heads 204 a,b, respectively.

FIG. 18 is a rear view of the suction mount 168.

FIG. 19 is a cross sectional view of the bonding system 100 taken alongline 19-19 in FIG. 2. As illustrated in FIG. 19, in various embodiments,the housing 102 includes a rear UV light shield 1916 within the chamber104 adjacent to the back side 120 of the housing 102. The rear UV lightshield 1916 may engage the back plate 134 and be utilized to align theback plate 134 with the housing 102.

The water meter register housing 174 is positioned on the gripper 156 ofthe positioner assembly 150 with the holders 166 in the releasedposition. The glass 176 is centered on the water meter register housing174 through a centering device (not illustrated), such as a centeringring or any technical equivalent. As illustrated in FIG. 19, the watermeter register housing 174 is positioned on the gripper 156 such thatthe suction cup 180 is positioned in the wiring port 1912. The suctioncup 180 in the wiring port 1912 seals the wiring port 1912, therebysealing an interior 1918 of the water meter register housing 174. Asillustrated in FIG. 19, the holders 166 of the gripper 156 are moved tothe gripped position such that the holders 166 engage the water meterregister housing 174 and retain the water meter register housing 174 inplace.

A vacuum is applied within the interior 1918 of the water meter registerhousing 174 through the suction mount 168 and suction cup 180 connectedto the vacuum pump as described above. As illustrated in FIG. 19, thesuction cup 180 includes the opening 1904 in fluid communication withthe vacuum channel 1606 of the suction mount 168 such that air may bepulled from the interior 1918 of the water meter register housing 174,through the wiring port 1912, through the opening 1904 of the suctioncup 180, through the vacuum channel 1606 of the suction mount 168,through the vacuum connector 178 and tubing, and outside of the chamber104. The vacuum created within the interior 1918 and underneath theglass 176 via the vacuum connector 702 may retain the glass 176 in placeon the water meter register housing 174. Accordingly, in variousembodiments, after the vacuum is created within the interior 1918, thecentering device may be removed.

As illustrated in FIG. 19, while the vacuum is applied within theinterior 1918 of the water meter register housing 174, the water meterregister housing 174 and glass 176 are vertically raised within thechamber 104 through the elevating mechanism 154 of the positionerassembly 150 to position the water meter register housing 174 and glass176 relative to the dispenser 106 and curing devices 108. A vacuum isapplied within the chamber 104 when the door 192 is in the door closedand sealed position as illustrated. Accordingly, in various embodiments,two vacuums are applied within the housing 102: a first vacuum withinthe interior 1918 of the water meter register housing 174 and a secondvacuum within the chamber 104 and exterior to the interior 1918 of thewater meter register housing 174. In various embodiments, the firstvacuum is about the same as the second vacuum. In various otherembodiments, a differential in vacuum may exist between the first vacuumand the second vacuum. The vacuum differential between the first vacuumand the second vacuum may aid in dispensing of the adhesive agent, asdescribed in greater detail below.

FIG. 20 is a detailed view of the bonding system 100 taken from detail20 in FIG. 19. The glass 176 positioned on the water meter registerhousing 174 defines a location where the adhesive agent is to bedispensed and cured. As illustrated in FIG. 20, the water meter registerhousing 174 and the glass 176 are vertically positioned within thechamber 104 such that the curing devices 108 and dispenser 106 arealigned with the adhesive agent is to be dispensed and cured. In thepresent embodiment, the location where the adhesive agent is to bedispensed and cured is a groove 2008 defined by the water meter registerhousing 174 and glass 176. In various embodiments, the elevatingmechanism 154 vertically raises the glass 176 and water meter registerhousing 174 such that the glass 176 engages the securing plunger 808.The securing plunger 808 may aid in positioning the glass 176 on thewater meter register housing 174 while permitting the glass 176 andwater meter register housing 174 to rotate. In various embodiments, thesecuring plunger 808 may be constructed from a plastic or various othermaterials suitable for positioning the glass 176 on the water meterregister housing 174 while permitting rotation of the glass 176 andwater meter register housing 174.

As illustrated in FIG. 20, the emitting ends 806 of the curing devices108 and the dispensing end 804 of the dispenser 106 are aligned with thegroove 2008. In various embodiments, the securing plunger 808 may retainthe glass 176 in position on the water meter register housing 174 as theadhesive agent is dispensed and cured. In various embodiments, each ofthe dispenser 106 and the curing devices 108 a,b,c are aligned withdifferent portions of the groove 2008. For example, in variousembodiments, the dispenser 106 and curing device 108 a may be positionedand aligned with opposite sides of the groove 2008 with the UV shield148 positioned between the dispenser 106 and the curing device 108 a. Invarious other embodiments, the dispenser 106 and the curing devices 108a,b,c may be aligned with various other portions of the groove 2008.

As illustrated in FIG. 20, the sealing plug 1910 b is positioned in theplug cavity 1214 b of the dispenser bore 1106 to seal the dispenser bore1106 around the dispenser 106. In various embodiments, an O-ring 2010 isutilized to form a seal between the curing bore 1104 a and the curingdevice mount 142 a and the O-rings 2012 a,b are utilized to form a sealbetween the curing device 108 a and the curing device mount 142 a.

In various embodiments, after the groove 2008 is aligned with thedispenser 106 and the curing devices 108, the bonding system 100 beginsdispensing the adhesive agent through the dispenser 106. While thedispenser 106 dispenses the adhesive agent, the rotator 152 rotates theglass 176 and water meter register housing 174 such that the adhesiveagent is dispensed along an entirety of the groove 2008. The adhesiveagent may be dispensed as a bead of material. In various embodiments,one pass of dispensing the adhesive agent includes rotating the glass176 and water meter register housing 174 about 360° through the rotator152. In various embodiments, dispensing of the adhesive agent includesmaking two passes with the adhesive agent: a first pass includesdispensing the adhesive agent while rotating the glass 176 and watermeter register housing 174 about 360° clockwise and a second passincludes dispensing the adhesive agent while rotating the glass 176 andwater meter register housing 174 about 360° counterclockwise. The numberof passes, the speed of rotation, or the degrees of rotation disclosedshould not be considered limiting on the current disclosure.

After the desired amount of adhesive agent has been dispensed, theadhesive agent in the groove 2008 is activate for curing through the UVlight emitted by the curing devices 108. In various embodiments, whilethe curing devices 108 directs the curing catalyst activation source tocure the adhesive agent in the groove 2008, the rotator 152 rotates theglass 176 and water meter register housing 174 such that the curingdevices 108 cure the adhesive agent along the entirety of the groove2008.

FIG. 21 is a detailed view of the bonding system 100 taken from detail21 in FIG. 20. As illustrated in FIG. 21, the water meter registerhousing 174 and glass 176 are positioned within the chamber 104 suchthat the dispensing end 804 of the dispenser 106 is aligned with thegroove 2008. As illustrated, the groove 2008 includes a top portion2102, a pinch point 2104, and a bottom portion 2106.

In various embodiments, the first bead of adhesive agent is administeredduring the first pass. The first bead remains substantially in topportion 2102 and the pinch point 2104 of the groove 2008 until the endsof the first bead meet (i.e. when the start of the bead meets the end ofthe bead). When the ends of the first bead meet after the first pass ofdispensing, the first bead may form a hermetic seal. The first bead ofadhesive agent may move from the top portion 2102 and the pinch point2104 into the bottom portion 2106 of the groove 2008 underneath theglass 176. Movement of the first bead may be partially attributable togravity in various embodiments. A second bead of the adhesive agent maybe dispensed during a second pass to fill the pinch point 2104 and thetop portion 2102 of the groove 2008. Positioning of the second beadwithin the groove 2008 may be partially attributable to gravity.

As previously described, in various embodiments, a vacuum differentialexists between the first vacuum within the interior 1918 and the secondvacuum within the chamber 104. In various embodiments, the first vacuumwithin the interior 1918 is at least slightly stronger than the secondvacuum within the chamber 104. In these embodiments, the vacuumdifferential may aid in pulling the first bead of the adhesive agentinto the bottom portion 2106 of the groove 2008. Accordingly, in variousembodiments, movement of the first bead may be partially attributable tothe vacuum differential.

The positioning of the adhesive bonding material as described may reducethe potential for air bubbles to form in the adhesive bonding materialduring the curing process. During a typical bonding process, theadhesive bonding material is dispensed in the groove 2008 but does notcompletely fill the groove 2008. Because the adhesive bonding materialdoes not completely fill the groove 2008, air voids are formed withinthe adhesive agent. Operators may work to rupture the air voids, oftenby hand, during a time-consuming process. However, these air voids arenot always found during the curing process and any entrapped air voidshave the potential to become a leak path. The bonding system 100addresses this problem by dispensing the adhesive agent such that theadhesive agent substantially fills the groove 2008, thus reducing thepotential for air voids and leak paths. The process performed by thebonding system 100 encourages a uniform application of the adhesiveagent so that the adhesive agent is uniformly applied all along the edgeof the glass 176. The bonding system 100 also encourages a uniformapplication of the adhesive agent within the groove 2008 all along thegroove 2008 where the glass 176 and water meter register housing 174 areto be joined in various embodiments. The uniform application of theadhesive agent along the edge of the glass 176 may create a consistentseal along the edge of the glass 176 when the adhesive agent is cured.The uniform application of the adhesive agent may create a consistentseal along the position where the glass 176 and water meter registerhousing 174 are joined.

In various embodiments, the dispensing of the adhesive agent in vacuumconditions within the chamber 104 may minimize the air voids in theadhesive agent because the adhesive agent is encouraged to fill theintricate geometries of the groove 2008. The reduction in air voids isbeneficial to the assembled strength of the bonded glass 176 and waterregister housing 174.

During a typical bonding process, the dispensing and the curing stepsoccur in different environments or the curing may take place in anambient environment. In either instance, the adhesive agent may beexposed to various contaminants that the adhesive agent may absorb. Thedispensing and curing of the adhesive agent under vacuum conditionswithin the chamber 104 may minimize the adhesive agent's absorption ofcontaminants. In various embodiments, the dispensing and curing of theadhesive agent under vacuum conditions within the chamber 104 mayimprove the density of the adhesive agent in the groove 2008 andaccordingly improve the strength of the bond.

After dispensing of the adhesive agent has ended, the adhesive agentwithin the groove 2008 is activated for full or partial curing throughuse of the curing devices 108. As previously described, at least onecuring device 108, such as the curing device 108 a, is angled withrespect to the vertical axis 172 of the housing 102 through the curingbore 1104 a. Accordingly, the curing device 108 a is also angled withrespect to the groove 2008. Because the curing device 108 a is angled,the curing catalyst source emitted from the curing device 108 a may moreefficiently cure the adhesive agent in the groove 2008. For example,because the UV light directed from the curing device 108 a is angled,the UV light is able to illuminate and activate the curing of theadhesive agent in all portions of the groove 2008. The angled light maytravel directly to and illuminate the adhesive agent in the top portion2102, the pinch point 2104, and the bottom portion 2106 at the same timewith equal intensity through the glass 176. By comparison, the UV lightemitted from a non-angled curing device 108, such as the curing device108 b, travels through the adhesive agent in the top portion 2102 andpinch point 2104 before it may reach the bottom portion 2106.Accordingly, the UV light that travels through the top portion 2102 andpinch point 2104 to reach the bottom portion 2106 may have a reducedcuring activation effectiveness by the time it reaches the bottomportion 2106. Therefore, the angled light from the angled curing device108 a may more efficiently cure the adhesive agent in the groove 2008.

When the UV light is not angled, if the water meter register housing 174is constructed from UV resistant plastic or metal, the UV light would beblocked by the UV resistant material and the adhesive agent is lessefficiently cured. When the UV light is angled through the emitting end806 a, the UV light may be focused through the glass 176 to moreefficiently cure the adhesive agent in the groove 2008 and accordinglyfacilitate the use of the UV resistant plastic or metal for the watermeter register housing 174. Additionally, the angled UV light mayfacilitate the use of a plastic or translucent housing having a colorthat is near the light spectrum required by the adhesive agent for itsactivation and curing. For example, when the UV light is not angled, acolor that is near the light spectrum required by the adhesive agent mayblock the UV light such that the adhesive agent is less efficientlycured.

The dispensing and curing of the adhesive agent under vacuum conditionswithin the chamber 104 may improve the density and minimizecontamination of the adhesive agent, which may be suitable forcomponents joined for various applications. As a non-limiting example,the adhesive agent may provide: improved strength for components such asundersea electrical connectors; improved performance and efficiency offiber optic connectors; improved performance and efficiency ofmunitions; and improved performance and efficiency of ballistic systems.

FIG. 22 illustrates a bonding system 100′ according to anotherembodiment of the current disclosure.

FIG. 30 illustrates steps of the dispensing process 2806 according tovarious embodiments. In step 3002, the dispenser 106 at least partiallypositioned within the chamber 104 begins dispensing the adhesive agentat the location where the first item and second item are to be bonded.In various embodiments, where the first item and the second item are thewater meter register housing 174 and the glass 176, respectively, thelocation where the first item and second item are to be bonded is thegroove 2008. In step 3004, while the dispenser 106 is dispensing theadhesive agent, the positioner assembly 150 rotates the first item andsecond item 360° clockwise. In various embodiments, the rotator 152rotates the first item and the second item. As described above, duringthis first pass of dispensing, the adhesive agent may remain in topportion 2102 and pinch point 2104 of the groove 2008 until the ends ofthe bead of adhesive agent meet after the full rotation is complete.After the ends of the bead of adhesive agent meet, the adhesive agent ispulled into the bottom portion 2106 of the groove 2008.

In step 3006, after the rotation of the first item and the second item360° clockwise, the positioner assembly 150 rotates the first item andthe second item 360° counter-clockwise. As described above, during thissecond pass of dispensing, the adhesive agent may be positioned in thepinch point 2104 and the top portion 2102 of the groove 2008 to fill thegroove 2008 with the adhesive agent. In step 3008, the dispenser 106 maystop dispensing the adhesive agent. In various other embodiments, step3004 and step 3006 may be reversed such that step 3006 is the first passof dispensing and step 3004 is the second pass of dispensing. The numberof passes of dispensing or the degrees of rotation during each passshould not be considered limiting on the current disclosure. The speedof rotation and adhesive dispensing may be adjusted to control theplacement of the adhesive agent in the groove 2008.

FIG. 31 illustrates steps of the curing process 2808 according tovarious embodiments. In step 3102, the UV curing activation source, suchas the UV light curing sources 2204, are turned on such that UV light isemitted by the curing devices 108 positioned at least partially withinthe chamber 104. In step 3104, while the curing devices 108 emit the UVlight, the first item and the second item are rotated in the chamber 104through the positioner assembly 150. In various embodiments, the rotator152 rotates the first item and the second item. The first item andsecond item are rotated 360° in a first direction. The speed of rotationmay be controlled depending on whether the operator wants to partiallycure the adhesive agent or fully cure the adhesive agent.

In step 3106, it is determined whether the adhesive agent issufficiently cured. In various embodiments, the adhesive agent may besufficiently cured depending on whether the operator wants to fully curethe adhesive agent or partially cure the adhesive agent. In variousembodiments, the adhesive agent is sufficiently cured if it is at leastpartially cured to a desired degree. If the adhesive agent is notsufficiently cured, in step 3108, the adhesive agent continues to beexposed to the UV light while the first item and second item are rotated360° in a direction opposite of the direction of the last rotation. Ifthe adhesive agent is sufficiently cured, in step 3110, the UV curingsource is turned off and the positioner assembly 150 stops rotating thefirst item and the second item. The disclosure in the step 3108 of a360° rotation in a direction opposite of the direction of the lastrotation, however, should not be considered limiting on the currentdisclosure.
